Routing MIDI channels
The MIDI processing block between MIDI IN and MIDI OUT connectors is called a “filter/router” : it not
only
filters out
certain MIDI message types or channels, but it can also
route
one MIDI channel to
another. If for instance you have one master keyboard which you want to use to play several synth
modules, you can copy the MIDI messages sent on one channel to a second channel in order to play
both synths at the same time. If instead you want to switch from one synth to another you can do that
by moving the incoming messages of the master keyboard to a different channel. The messages to
setup such channel routing are :
MoveChannel
channelname1
to
channelname2
CopyChannel
channelname1
to
channelname2
This channel routing (or the channel filtering of previous chapter) can be undone with the command
ResetChannelRouting
5.6.4.
Filtering or routing MIDI notes
This functionality can be of great use for keyboard players. It can turn a very simple MIDI keyboard into
a powerful master keyboard with several zones controlling several synth modules, adding transpose
functionality, and so on.
BlockNotes
channelname from-till
This command blocks a certain zone of the keyboard. The range is not expressed using numeric values
but using notes on the keyboard, ranging from C-1 to G9
MoveNotes
channelname from-till
to
channelname [from]
CopyNotes
channelname from-till
to
channelname
[from]
These commands are without doubt more interesting. They allow to move a certain zone of the
keyboard to a different channel, thus playing one synth module with one hand, and another synth
module with the other hand. On top of that you can specify a new “from” value for the moved or
copied range, which results in transposing the played notes.
A sample syntax is :
MoveNotes synth1 C4-G9 to synth2 C3
The MIDI note filtering or routing can be undone with the command
ResetNoteRouting
